Patented Feb. 4, 1908.

Application filed January 7, 1907. Serial No. 351.190. Renewed December 26. 1907. Serial No. 408.268.

To all whom 'it may concern. i

Be it known that I, GEORGE WOLKE, a citil zen of the United States, residing at Jacksonl ville, in the countyY of Morgan and State of Illinois7 have invented certain new and usci inl Improvements in Governor and Valve, Movements; and I do declare the lollovvingjy i to be a full, clear, and exact description oi' the invention, such as will enable others skilled in the art to which it appertains to make and use the same` This invention relates to`governors employed upon engines of various kinds, and more particularly to the class of interior combustion or similar motors, and has for its object to. improve the construction and increase character.

TWith these and'othcr objects in view which will appear as the nature ol the invention is better understood, the invention consists of certain novel .features ol construction, as hereafter shown and described and spccilically pointed out in the claims.`

In the drawings accon'ipanyini; this specification and forming a part ol thc saine is illustrated a preferred torni o'l' thc embodiment the invention capable ol" carryingr the same into Iractical o eration.

In the rawings thus employed, lligure l is a sectional vieivol` portions of a conventional explosive or similar combustion engine, together with the' niain shalt, ily wheel, and one of theve-lves. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view in elevation oi the hub portion ol' the ily-wheel and adjacent parts. Fig. 4 is a detail view olxv one of the toothed-annular, disk-members 5 is a similar view of the other toothed, annular, disk-inember- In the drawings, the cylinder oi the engine is represented at l0, the hood through which the main shaft ll is journaled is represented ily wheel at 14, all of these parts being ol' the usual construction. At. one end, the cylinder 10 is provided with a head 15 having the f usual recesses 16 for the coolingl air, and with spaced spring supported inlet and exhaust valves l7-l8 of the usual construction, the valves being operative from the exterior oi the head, as shown. Extending from the head Yl5 isa standard lli in which a lever 20 is pivoted at 2], the shorter end bearing over 55 the valve 18 and. adapted to operate the valve when lthe lever isactuated, as hereafter explained.

A hood l2 is provided with the usual bearings 22-23 for the shaft 1l, and extending l60 from the bearing 23 Ais a casing 24, the casing inclosing' the shaft `11 and provided .at its outer side with a YIiange or collar 25,

ner faces corresponding to the conical facesA of the eccentric, and bolted together at `31 u'ion the eccentric. B this sim )le lnea'ns`u75 l y i the two annular members are firm y clamped to the eccentric, while the latter is `free to.ky rotate within thc members, as willbe obvious. The disk 2Q is provided with spaced teeth 32 upon its periphery, while the disk 30 is pio\-.\ 80 vided with tecth 2553 upon its periphery, the

teeth 33 being one-half in number to-the teeth 32, or in other Words, the disk 29 is provided with just twice as many teeth as the disk 30. in outline, while the teeth 33 are formed with fiat contiguous edges, and segmental outer laces, as shown rcs ectively in Figa and 4. .Projecting witiiin the casing 24 are spaced rollers 34-35, lthe rollers being so 90 located that they engage the teeth 32 one at a tinic :it alternate sides as the disks are actuated by the rotation of the eccentric and thus rotate the disks intermittently, as will bc obvious. in closed position by the action oi its spring,

and thus holds the lever -20 also with its outer end pressed rearwardly and with the inner cnd oi thc rod 26 1n its inward position and within one olc the intcrstices between the 100 teeth 33, as shown in Fig. 1. When the eccentric 28 is disposed with lits shorter side toward the rod 26, the disks 29-30 will occupy a position with the teeth 33 out of contact with the inner end of the rod 26 105 when the latter is in its normal position, as shown in Fig. 1, and the continued movements oi the eccentric (co-acting with the Operating through one side of the Bearing upon the doubly conical The teeth32 are semicircula12"85 The valve 18 is held normally 95 rollers s4s5 win rosa@ the disks ,the distance of one of the teeth 32 at each half-revolution of the eccentric. By this means, it

' will be obvious that the teeth 33 ot the disk 30 when the disk is in one position will pass the rod 26 'without affectingt, the object to be hereafter explained.

Pivoted at36-37 to the collar 25 is a yoke 38 having an arm 39 extending therefrom,

' Wheel 14 is a yoke 46 adapted to contact with the yoke 38 for operating the same when the yoke 46 is actuated. Extending at an angle from the yoke 46 is an arm 47 terminating in a relatively large ball 48, the

" ball having ears 49-,50 extending from its sides` to support the outer ends of springs 51-52, the inner end 'of the springsbeing connected at 53-54 to the hub 45 of the fly I wheel, the springs operating to hold the.

Weighted arm 47 and the oke'46 ieldably in withdrawn position, wit the yo e 38 out of action.

Vith a device thus described, the oper ation. is as follows: The toothed 'disk' 29 having twice as many teeth as the toothedv disk 30, causes the latter to push back the rod 26 and operate the valve 18 through the -lever 20 at every alternate revolution of' the engine, as the inner end of the rod bears on one'o the teeth 33 during one revolutlon and within one of the spaces between. the' teeth during the next revolution, thus Inakin the requisite two to one motion, as wil be obvious. So long as the engine is running at normal speed, this uniformity of action will be maintained, as the spring 42 holds the vyoke 38 and its arm 3S) in vtheir outward or in-o )erative position, while the springs 51-52 li ewise hold the yoke 46 and its weighted arm 47 48 in withdrawn or inoperative position. In event of abnormal increase of speed, the weighted lever 47-48 will be .drawn inward by the centrifugal force, causing the yoke 46 to bear against the yoke 38 and depress the point 4] of the arm 39 against the rod 26 am cause it to engagev the sto 40 at the first outward movement of the ro and thus hold thc valve 18 in open position and reducing the pressure in the cylinder and thereby decreasing the'speed until it again reachesnormal, when the return of the weighted level 47-f-48 to its normal position tlirough the influence ol" the springs 517-52 will releasc'theyoke 38 and permit its slpring 42 to .again throw the arnr 39 outward y and release ,the rod 26.

By this means, it will be obvious that a applied to an engine having coo ing chambers i associated therewith, it willl be understood that thedevice is equally applicable to other y forms of cylinder orl those not having the "i cooling compartments. y
